Title: FIN AND HEAT EXCHANGER HAVING SAME
Abstract:
A fin (10) and a heat exchanger having the fin (10) are provided. The fin (10) comprises a fin body (11). The fin body (11) comprises multiple heat dissipation fin units (100) arranged along a longitudinal direction of the fin body (11). Each heat dissipation fin unit (100) comprises a heat transfer section (110) and a first side section (120) that are arranged along a lateral direction of the fin body (11). The first side section (120) is located on an airflow-facing side relative to the heat transfer section (110). The first side sections (120) of adjacent heat dissipation fin units (100) meet each other to extend continuously along the longitudinal direction. A slot is formed between the heat transfer sections (120) of adjacent heat dissipation fin units (100). The heat transfer section (110) is provided with a first water guide protruding strip (111) that extends downwards from the heat transfer section (110) to the first side section (120) in a direction inclined relative to the lateral direction of the fin body (11). At least a part of an airflow-facing portion of the first water guide protruding strip (111) extends into the first side section (120). The fin (10) and the heat exchanger with the fin (10) of the present invention can improve performance in discharging condensate, and reduce blockage caused by a frost layer, improving heat exchange efficiency.
